Robotic walking training boosts recovery in stroke patients with muscle loss

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

\- Inclusion Criteria Participants must meet all of the following criteria: 1. Diagnosis of stroke within 6 months of onset (subacute phase), corresponding to the active neurological recovery period. 2. Classified as having possible sarcopenia according to the Asian Working Group for Sarcopenia (AWGS 2019) algorithm, defined by: * A positive SARC-F screening, and * Either reduced handgrip strength (men \<28 kg, women \<18 kg) or reduced physical performance (SPPB score \<9). 3. Height between 140 and 190 cm and body weight ≤80 kg, meeting the mechanical fitting requirements of the overground wearable gait robot used in this study. 4. Functional Ambulation Category (FAC) score ≥1, indicating the ability to attempt ambulation with at least minimal assistance. 5. Korean version of the Mini-Mental State Examination (MMSE-K) score ≥24, indicating sufficient cognitive ability to understand instructions and participate in training. 6. Currently admitted for inpatient rehabilitation at a rehabilitation hospital in Seoul, Republic of Korea. 7. Ability and willingness to provide written informed consent after receiving a full explanation of the study procedures, potential risks, and benefits. * Exclusion Criteria Participants will be excluded if they meet any of the following criteria: 1. Presence of severe cardiovascular disease (e.g., unstable angina, heart failure, recent myocardial infarction) or acute medical infection that contraindicates exercise-based interventions. 2. Musculoskeletal conditions that preclude safe participation in robotic gait training or recumbent cycling, including: * Lower extremity fractures, * Severe joint contractures, * History of lower limb joint replacement, * Structural deformities of the lower extremities. 3. Severe communication, psychological, or psychiatric disorders (e.g., global aphasia) that impair the ability to follow instructions or complete assessments. 4. Participation in robot-assisted gait training or similar mechanically assisted rehabilitation interventions within the past 6 months prior to enrollment.
